Media type: E-Article Title: UV imaging based on AlGaN arrays Contributor: Duboz, Jean‐Yves; Brault, Julien; Truffer, Jean‐Patrick; Robot, Jean‐Alexandre; Robin, Kristelle; Reverchon, Jean Luc imprint: Wiley, 2009 Published in: physica status solidi c Language: English DOI: 10.1002/pssc.200880764 ISSN: 1862-6351; 1610-1642 Keywords: Condensed Matter Physics Origination: Footnote: Description: <jats:title>Abstract</jats:title><jats:p>AlGaN Schottky photodiode arrays have been fabricated and hybridized to a commercial Si read out circuit. The array has been characterized in terms of current, spatial and temporal noise, and spectral responsivity. The array sensitivity was compared to the one expected from the performance of individual pixels, leading to the conclusion that the sensitivity of the array is currently limited by the read out circuit. Images are demonstrated with various arrays fabricated with different cut off wavelengths from 360 to 290 nm. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p>
